Application filed. September My invention relates to improvements in internal combustion engines and more particularly to that class of improvements which employs rotary motion in the functioning of their working'parts, and the objects of my invention are'to provide mechanism that'will increasecthe ratio of crank leverage to the stroke of theipiston, that, when desired, will permit such proportional combination of its I functions 'as'toc operate on the Otto or four cycle principle in such manner as to produce an explosion in each cylinder during each revolution ;of the mainbr drive shaft, that will more flexibly absorb the power impulse I 7 from the cylinder for working force, that will employ-higher piston speed at any-speed of the drive shaft as compared to the standard type of engine, that will o'perateby rotary motions as. a means ,of neutralizing vibration caused vby reciprocating-pistons and other working parts, that will permitof the eliniination of'gears, and cam-sl1aft,when-desired; that will simplify construction, shorten the a length and lighten the weight as compared to '25 the standardforms of engines, and lessen the strain on their working parts and frame, that will supply an air cooling process for the cylinders and that will obtain higher thermal and mechanical efliciencies than obtains in internal combustion engines commonly in use, and other objects,

I attain these ob'ects bythe mechanism illustrated in the accompanying drawings in which, Fig. 1 is a back view of the engine,

and Fig. 2 is a cross sectional view on theline Similar; numerals refer to similar parts throughout the several views.

The sides ,1 1, secured to the base 2, with the bolts 3 3, constitute the main framework oftheengine. v f

The fixed crank-shaft 4, is-secured tothe frame sidel, by means of the sleeve 5, and the key 6. The rotatable frame 7 7 8,has providedin its side 8, the bearing 9, and has fixed. to its opposite side the drive shaft 10, by means of the bolts-11 11. The drive-shaft 10, is adapted to turn in the bearing 12, which is secured to the inner facing of the other I provided in the valve chambers 2626, while.

mainframe side 1, by the bolts 13 13, and the bearing 9 is fitted to the journal ofthe fixed crankshaft 4, thus producing bearings for therotatableframe"? 7 8, to rotate on the main frame 11 2.

Fixed to the rotatable frame 7 78, are the cylinders, 14 14, which are provided with pistons 15 15. The crank-shaft 16, is journaled in the rotatable frame 7 7 8', by means of the bearings 17 17 One piston 15, and the crankv pin 18 are connected to the master connecting rod 19,,and theother piston 15, is connected to the sleeve pin 20, by the connecting rod, 21, while the other crankvpin 22, of the crank-shaft 16, is connected to the crank-pin 44, of the fixed crankshaft 4, by the connecting rod 23, and the caps 24 24, and the bolts 2525. Cast on the sides of the cylinders 14 14, are the valve chambers 26' 26, into which are fitted the intake pipes 27 27, and theexhaust pipes 28 28. On the outer surface of the bearing 12, are the valve push-rod cams 29 29, on which the rollers 30 30, travel as the frame 7 7 8; rotates, thereby lifting the push-rod cams 31 31, and the poppetvalves which are the reaction of the valve push-rods is produced by the springs 32 32, which are compressed between the push-rod guides 33. 33 andthepush-rod spring seats 34 34..

The intake drumhead 36, is fixed to the sleeve 5, andthe outer ends of the intake pipes 27 27, communicate with the intake drum 35, which isr fixed to the rotatable frame side 8, and turns around the drumhead 36, into which is fitted the intake feed pipe 37.

Cast on one cylinder 14, are the lugs 38 38, to which are securedthe balance weights 39 39, by'the bolts40 40. Through the sides of the power chambers 41 41, are set the spark plugs 42 42, to'which are attached the ignition circuit wires 43 43.

As shown in the drawings, this engine is equipped with 'valvemechanism to operate on provided in said cylinder, a connecting-rod the Otto or four cycle principle and in operation it functions as follows:

A starting impulse is applied to the crankshaft16, causing it to rotate in a rightward direction in the bearings 17 17, which simultaneously causes reciprocation of the pistons 15 15, in the clinders 14 14, and the functioning of the valve mechanism While the revolving of the crank-pin 22, tends to increase the dimension from its axis to the axis of crankpin 44, which is opposed by the connecting rod 23, thereby transferring the power impulse to rightward circumferential motion at the bearings 17 17 and thus causing the rotatable frame 7 7 8, with its assembly to revolve in a rightward direction about its axis: concomitantly with this functioning the fluid for combustion is supplied to the cylinders through the feed intake pipe 37, the intake drum 85, the revolving sections of the intake pipes 27 27, and valve chambers 26 26, while the. continued rotation of the crankshaft 16, is maintained by the expansive pressures in the cylinders and the burnt gases are discharged through the exhaust pipes 28 28.
